Feb. 20 (UPI) -- Paulina Gretzky and fiancé Dustin Johnson are expecting baby No. 2.
Gretzky, a 28-year-old model and daughter of retired NHL star Wayne Gretzky, announced in an Instagram post that she's pregnant and expecting again with Johnson, a 32-year-old professional golfer.
"coming soon..." she captioned a photo of herself cradling her baby bump and holding up a photo of a sonogram.
Gretzky and Johnson, who won the Genesis Open golf tournament Sunday, are already parents to 2-year-old son Tatum. The couple got engaged in August 2013 after seven months of dating.
"Dustin's the best dad, he's my best friend. He's been so supportive with me and we're just there for each other," the model told ABC News in 2015.
"It's hard to describe, but just from the first day he's born, your perspective on life completely changes," Johnson added of parenthood. "He's kind of the only thing that's really important, and being there for him and being a role model for him."
"It kind of makes life a lot easier, I think, just because there's just one thing that's kind of all you think about," he added. "It definitely simplifies stuff."
Gretzky has appeared in several films, including Grown Ups 2, and modeled for Maxim and Golf Digest. She is the eldest child of Wayne Gretzky and Janet Jones, who are also parents to daughter Emma and sons Ty, Trevor and Tristan.
